Abstract
Abstract A novel method for performing intraocular surgery is described in which a radial incision is first made in the sclera of the eye, a subsurface scleral pocket lateral and anterior to the radial incision is then created, the subsurface scleral pocket extending anteriorly to the cornea of the eye, and finally a transverse incision is made from the pocket through the cornea into the anterior chamber of the eye. Through these incisions a damaged lens can be efficiently and effectively removed and replaced with a new lens. Various post-operative benefits are observed as a result of employing this procedure.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
86 words
A method for performing intraocular surgery comprising the steps of: (a) making a radial incision into the sclera of an eye at a depth of less than the thickness of the sclera; (b) creating a subsurface scleral pocket lateral and inferior to said radial incision, said pocket extending inferiorly a distance to about the cornea of said eye; (c) making a subsurface transverse incision through said cornea into the anterior chamber of said eye from said pocket; and (d) performing a surgical procedure in said eye.
Claim 2
Independent Claim
86 words
A method for performing intraocular surgery comprising the steps of: (a) making a radial incision into the sclera of an eye at a depth of less than the thickness of the sclera; (b) creating a subsurface scleral pocket lateral and inferior to said radial incision, said pocket extending inferiorly a distance to about the cornea of said eye; (c) making a subsurface transverse incision through said cornea into the anterior chamber of said eye from said pocket; and (d) performing a surgical procedure in said eye.
Claim 3
Dependent Claim
23 words
The method of claim 1 wherein said surgical procedure in step (d) comprises the step of removing the natural lens of said eye.
Claim 4
Dependent Claim
33 words
The method of claim 2 wherein said surgical procedure in step (d) further comprises the step of inserting an artificial lens in said eye in the position previously occupied by the natural lens.
Claim 5
Dependent Claim
16 words
The method of claim 1 wherein said sub-surface scleral pocket is about 4.0 mm in diameter.
Claim 6
Dependent Claim
23 words
The method of claim 1 wherein said radial incision is located superior to the iris and along the medial plane of said eye.
Claim 7
Dependent Claim
15 words
The method of claim 1 wherein said intraocular surgery is carried out without incisional sutures.
Claim 8
Dependent Claim
16 words
The method of claim 2 wherein said sub-surface scleral pocket is about 4.0 mm in diameter.
Claim 9
Dependent Claim
23 words
The method of claim 2 wherein said radial incision is located superior to the iris and along the medial plane of said eye.
Claim 10
Dependent Claim
15 words
The method of claim 2 wherein said intraocular surgery is carried out without incisional sutures.
Claim 11
Dependent Claim
16 words
The method of claim 3 wherein said sub-surface scleral pocket is about 4.0 mm in diameter.
Claim 12
Dependent Claim
23 words
The method of claim 3 wherein said radial incision is located superior to the iris and along the medial plane of said eye.
Claim 13
Dependent Claim

The method of claim 3 wherein said intraocular surgery is carried out without incisional sutures.
Claim 14
Dependent Claim
22 words
The method of claim 1 wherein said subsurface transverse incision is between about 3.0 mm and about 5.0 mm in cord length.
Claim 15
Dependent Claim
25 words
The method of claim 1 wherein said radial incision forms a scleral orifice having a depth of about two-thirds of the thickness of said sclera.

Claim 18
Dependent Claim
25 words
The method of claim 2 wherein said radial incision forms a scleral orifice having a depth of about tow-thirds of the thickness of said sclera.
Claim 19
Dependent Claim
21 words
The method of claim 2 wherein said radial incision is between about 2.5 mm and about 4.0 mm in cord length.
Claim 20
Dependent Claim
22 words
The method of claim 3 wherein said subsurface transverse incision is between about 3.0 mm and about 5.0 mm in cord length.
Claim 21
Dependent Claim
25 words
The method of claim 3 wherein said radial incision forms a scleral orifice having a depth of about two-thirds of the thickness of said sclera.
